Tagiru is energetic, reckless and something of an airhead, and he always leaps into action without thinking. Even so, he is willing to risk anything to protect others. He is a member of the Xros Heart street basketball team alongside Kudou Taiki and Amano Yuu, and is in the same class as the latter.

Tagiru learned of Digimon and DigiQuartz by accident, unintentionally following Mogami Ryouma and his team into DigiQuartz and witnessing them attempt to hunt a Metal Tyranomon. He was roped into taking up Digimon Hunting by Gumdramon, who initially intended to use Tagiru to his own advantage before having a change of heart, and received a Xros Loader from a reluctant Watch Man, before learning of Taiki and Yuu's history with Digimon and joining with them to hunt. His goal is to surpass Taiki, much as Gumdramon's is to surpass Shoutmon.
